Thermapen

I have a friend who needs a lot of par baked bread on hand but I have been having difficulty getting the bread out at 90% baked, usually 180 F. My thermometer takes about 20 seconds or longer to show the temperature and with differing temperatures in the kitchens it's all across the scale unfortunately.

So I am looking at a Thermapen[1], it is expensive (120.00 CAD) but it measures temp in 4 seconds and has a good range too, -50 to +570 F.

Anyone use this item or a similar thermometer with a short temp measurement?
